Bit Shift
Performs a logical or arithmetic shift of the input signal.
blockType: Bit Shift

Description
Block Bit Shift performs a logical or arithmetic shift of the input signal.
The behavior of this block in modeling and code generation differs from the block Shift Arithmetic.
Block Shift Arithmetic shifts the bits or the binary point of the input number. This block has additional options for code generation compared to the block Bit Shift. When it is necessary to perform a variable shift operation, use the block Shift Arithmetic instead of a block Bit Shift. If a signed number is entered, the block expands the signed digit.
